    Hi Readers!
    In this blog you can find both versions (Obj C & Swift) for converting NSData to NSString or vice-versa.

    Objective C

    NSString * str = @"Hello";
NSData * data =[str dataUsingEncoding:NSUTF8StringEncoding];
NSLog(@"Data = %@",data);

NSString * convertedStr =[[NSString alloc] initWithData:data encoding:NSUTF8StringEncoding];
NSLog(@"Converted String = %@",convertedStr);

    Output:

    Data = <48656c6c 6f>
    Converted String = Hello

    Swift

    var str = "Hello"
var data = str.dataUsingEncoding(NSUTF8StringEncoding, allowLossyConversion: true)
println("Data = \(data)")

var convertedStr = NSString(data: data!, encoding: NSUTF8StringEncoding)
println("Converted String = \(convertedStr)")

    Output:

    Data = Optional(<48656c6c 6f>)
    Converted String = Optional(Hello)
